Bright Sword: Starting from the Improved Grenade

"Why is there no one here? Commander, I think we should go find Captain Li and ask him!"

Looking at the empty arsenal, the young guard said a little worriedly.

"Need not."

The middle-aged man shook his head. Just when they were approaching the arsenal, soldiers from the New Regiment checked it out, which meant that the place was tight inside and there would be no danger.

"There's smoke ahead, let's go check it out!"

Following the trail of smoke, the two men bypassed the arsenal and came to a wooden house. Seeing the wooden door wide open, they walked in.

In the kitchen, Zhao Tianyang was sweating profusely as he held a bamboo stick covered with pulp and stirred the big pot in front of him. When he heard someone coming in, he handed the bamboo stick over without caring who it was.

"Hurry up, help stir the lard. I'm so tired."

Seeing this, the middle-aged man was stunned for a moment, then he took the bamboo root with a smile and walked over to stir it.

"Sir, let me do it."

The guard, who was stunned by Zhao Tianyang's actions just now, had no time to scold Zhao Tianyang, and hurried forward to take the bamboo stick.

But the middle-aged man waved his hand and signaled him to go and make a fire.

The guard had no choice but to come to the stove with a wronged look on his face and add two pieces of firewood. He didn't want to remind this young man who looked a little reckless.

He wanted to see if Zhao Tianyang would panic after knowing who the person he had just ordered around was.

"Tons, tons, tons..."

Zhao Tianyang drank two large bowls of boiled water, breathed a sigh of relief, and then turned his gaze to the two people who had just come in.

Because the room was dim, he couldn't see any difference between the two men's uniforms.

Just by seeing the pistol on the young man who was burning the fire, I guessed that the two people in front of me should not be simple.

But he was not in a panic. With what he was doing now, not to mention the brigade commander, even the general manager would have to help him out.

"You two look unfamiliar. What are you doing in the new group?"

Zhao Tianyang held the bowl and asked tentatively while taking small sips.

"Haha, young man, the food in your new regiment is quite good. There must be two pigs in the pot to make the lard in it, right?"

The middle-aged man did not answer Zhao Tianyang's question, but asked back with a smile.

"Both ends?"

Zhao Tianyang rolled his eyes speechlessly: "Here is the lard from three pigs."

It's funny to say that he couldn't find any white pigs that could produce oil in Xingjiazhuang or the surrounding areas, so he could only use black pigs with more lean meat.

This kind of pig is native to China. It must be delicious when used for cooking. However, in terms of oil production, it cannot even catch up with white pigs.

He had to kill three black pigs to meet the needs of this experiment.

“Three heads!!”

The middle-aged man felt like his veins were about to burst. Li Yunlong ate better than him and the boss. Is there any law against this? ! !

"How come you guys are eating so well? Did you do anything out of the ordinary?"

The guard who was also shocked asked hurriedly, for he was afraid that if he didn't ask, the leader would lose his temper.

"What's out of the ordinary?"

The corner of Zhao Tianyang's mouth twisted, and he was about to start showing off.

"Our New 1st Regiment is very powerful. It's not easy for us to eat pork. We can just find a random enemy transport team and fight them. Then we will have everything."

"Boasting! Even our leaders dare not say that. We can easily defeat a Japanese transport team!"

The guard was dismissive.

The middle-aged man felt that Zhao Tianyang was not bragging. Although the time was short, on the way here, he had already observed that the soldiers on guard were all holding Type 38 rifles.

They had two or three grenades on their waists, and some soldiers even used tortoise boxes. He didn't believe that they had no strength, but he didn't know how strong they were exactly.

"Oh, really? Then do you know where your leader went today?"

The middle-aged man asked with a smile.

"Who knows."

Zhao Tianyang came to the big pot, looked at the melting of the fat inside, and replied casually.

"But what is certain is that Lao Li is now either leading his men to dismantle the enemy's railroad tracks or ambushing the enemy's transport team."

The expenses of the arsenal have been increasing these days, and Li Yunlong has been forced to spend twenty hours outside doing things.

"So busy?"

The middle-aged man was a little surprised. It seemed that Li Yunlong had a hard time too. He thought that he could take less when they met later.

"It's more than just busy. I sleep later than a dog and wake up earlier than a chicken."

While carrying out a large vat from the corner, Zhao Tianyang complained that if beating up the local tyrants wasn't too conspicuous, Li Yunlong would have started a bloody storm here long ago.

"Ah! Captain Li is so pitiful!"

The guard sympathized.

"How do you think such a large arsenal was built? It's all about money!"

As he spoke, Zhao Tianyang took the bamboo stick from the middle-aged man and put it aside. He picked up the ladle and scooped up a ladle of completely melted lard and was about to pour it into the large vat.

"What are you doing?"

The middle-aged man, who had been thinking about Li Yunlong's hard work and wanted to be nicer to him in the future, now grabbed Zhao Tianyang's hands with a look of fear on his face.

He just looked and saw that the big vat was full of dirty yellow water that was still steaming. This ladle of lard would be wasted!

"What are you doing? This lard is not for eating!"

Zhao Tianyang looked at the middle-aged man with a distressed look on his face and couldn't help but explain: "I use this lard to refine nitroglycerin, which is much better than satisfying my appetite!"

"Nitroglycerine?"

The middle-aged man looked at the simple environment in the kitchen and said nothing, but he said everything.

"You underestimated me!"

Zhao Tianyang explained as he scooped oil from the pot.

"The contents of my vat are all filtered and heated wood ash water. Once I pour this big pot of lard into it and let it sit and saponify, I will get glycerin and soap."

"I see."

The middle-aged man nodded. Indeed, the acquisition of glycerin was not very sophisticated.

But it is not so easy to turn glycerin into nitroglycerin. According to the information he has obtained so far, the arsenal does not have special equipment for synthesizing nitroglycerin.

"As far as I know, the Arsenal does not have a machine specifically for synthesizing nitroglycerin, even though you can already produce sulfuric acid and nitric acid."

“You know quite a lot!”

From the middle-aged man’s words and his round face, Zhao Tianyang had already guessed who this person was.

He suppressed his excitement and explained his plan with a bit of boasting.

"The most difficult part in making nitroglycerin is that when you drop glycerin into the mixed acid, excessive shock and temperature may detonate the nitroglycerin being produced."

Hearing this, the middle-aged man nodded silently. Indeed, this was the most difficult and important step in nitroglycerin.

"So I decided to use the power of nature and fill a ceramic basin with mixed acid at dawn every day when the temperature is low."

"Then half of the ceramic basin is placed in the stream and glycerine is slowly dripped in, so that the temperature inside the ceramic basin is always maintained at 16 to 20 degrees."

"Well, that's a good idea."

The middle-aged man's eyes lit up.

"Because it is in the stream, if the temperature rises and cannot be controlled, the basin can be directly sunk to the bottom of the water and people can avoid it, which can also avoid casualties to the greatest extent."

After saying this, the middle-aged man was still a little excited. That was nitroglycerin. Whether it was explosives or propellants, nitroglycerin was an important prerequisite technology!

He patted Zhao Tianyang's shoulder excitedly.

"Well done! Young man, let me introduce myself again. I am the commander of the 386th Brigade."
